ORIGINAL ARTICLE (see update below):
In the wildly popular Professor Layton puzzle games for the Nintendo DS and 3DS systems, the titular professor makes a name for himself solving the most curious mysteries throughout the land. The latest mystery revolves around the puzzle-solver himself, as word on the street has it that he may be coming to the Wii U and 3DS versions of Super Smash Bros. as an upcoming DLC character.

It should go without saying that this news, like any other rumor, should be taken with a grain of salt or two. However according to Twitter user @LaytonSmash, Christopher Robin Miller – who has lent his voice to Professor Layton in every English adaptation in the series – has kind of sort of maybe confirmed his inclusion in the game. The story goes like this: sometime in July, someone noticed Mr. Miller’s name on the Super Smash Bros. for Nintendo 3DS IMDb page, once again performing the part of Professor Layton (it’s still there, actually). When this was brought to his attention on Twitter, Miller replied saying that it simply wasn’t true.

That seemed to end the conversation until yesterday, when an unprompted Miller returned to that specific tweet to indicate that he was, in fact, providing his dulcet tones to the good professor once more, but in a more action-packed role.

The @LaytonSmash Twitter account has since been going a bit crazy, trying to work out if the new reply has been interpreted incorrectly and he’s not joining Super Smash Bros., or if Miller spilled the beans before he was supposed to. Miller’s Twitter account has long been protected, so only approved followers can see his tweets. Perhaps he doesn’t know how the internet works, and expected people to keep quiet if he gave them some inside info. Who’s to say?

Several non-violent characters such as Animal Crossing‘s Villager, the Wii Fit Trainer, and R.O.B. have all made surprise appearances in the series, and even Professor Layton‘s case-cracking counterpart Phoenix Wright had a chance to duke it out in 2011’s Ultimate Marvel vs. Capcom 3. Remembering this and the fact that Nintendo has been taking suggestions for new fighters in their Smash Bros. Fighter Ballot (which is still open until Oct. 3, by the way), anything is possible.

UPDATE:
Christopher Miller has replied to @LaytonSmash on the matter with a firm “I don’t know.” For now all we can do is wait for the next Smash Bros. Direct to see what Nintendo’s got in store for us.

I'll update you guys. This'll be the last word on this for now. In future I'll be a lot more careful when relaying. pic.twitter.com/74DtXiJeuC
